BRIDGEPORT -- A Fairfield man, accused of sexually assaulting a 13-year-old girl at a New Year's party and a 15-year-old girl who he met while horseback riding, was sentenced Friday to six years in prison.

Michael Ferguson, 26, maintained he never used force on the victims, but nonetheless agreed to plead guilty to second-degree sexual assault and risk of injury to a minor.

In a statement read in court by Supervisory Assistant State's Attorney Cornelius Kelly, the 15-year-old victim said her life was nearly destroyed by Ferguson's assault.

"The most vivid thing I remember from that night is him saying, `I told my friends I would never take a girl's virginity. Am I a liar?' and that is when I knew what kind of monster he really was," the victim stated. "I still remember feeling tears rolling down my face as I said, `What? No. No. Please no!' "

Superior Court Judge Robert Devlin sentenced Ferguson to 12 years, suspended after he serves six years, followed by 10 years' probation. He ordered Ferguson to register as a sex offender.

"Often, these cases have stark contrasts, but clearly this young woman has been dramatically affected by this," the judge said.

On Jan. 1, 2013, the 13-year-old girl had been attending a New Year's party at a friend's home in Fairfield when police said Ferguson had the girl smoke marijuana, then sexually assaulted her.

Following Ferguson's arrest in that case, police said they received a phone call from a woman who told them her daughter also had been sexually assaulted by Ferguson.
